Implementation of School Nutrition Policies to Address Noncommunicable Diseases in Uzbekistan and Kyrgyzstan

School nutrition policies are a promising approach to address the risk factors of noncommunicable diseases, but their large-scale implementation requires clear guidelines for coordination among various actors.

ranked as the number 1 and 2 drivers of deaths in Kyrgyzstan and Uzbekistan, respectively. 8,9In both countries, adults aged 20 years and older consumed an equivalent of 14.1g of salt per day (5.63 g of sodium)-2.5 times higher than the WHO-recommended limits of 5 g of salt per day (less than 2 g of sodium/day). 6,10hildhood exposure to NCD risk factors, including the adoption of unhealthy food behaviors and consumption of unhealthy diets that predispose to childhood obesity, leads to NCDs among children and the risk of developing NCDs later in life. 11,12hildren adopt unhealthy dietary behaviors (e.g., eating ultra-processed and calorie-dense snacks in between meals, consuming packaged sweetened drinks, and frequently eating highly processed burgers and pizzas with high levels of salts and saturated fats) earlier on. 13,14][17][18][19][20][21] Most children spend 6 hours or more in school and consume as much as half of their daily caloric intake at school. 22Moreover, schools provide constant access to children for health promotion initiatives. 23][24] In this article, healthy foods include recognizable naturally-occurring food ingredients (e.g., fruit, vegetables, legumes, whole grains, fish, lean meat, chicken, eggs, low-fat dairy) combined to provide 60-65 kcal/kg/day for children aged 6-8 years and 35-45 kcal/kg/day for children aged 9 years and older, such that the ratio of proteins, fats, and carbohydrates is set at 1:1:4, or 10-20%, 25%-30%, and 50-55% of the recommended caloric intake, respectively, 25 of which less than 10% of the carbohydrates is from free sugars, less than 10% of fats is saturated fats (e.g., fats found in fatty meat, palm oil, cheese), and less than 1% of the fats is trans fats (e.g., fats from baked and prepackaged snacks such as cookies and frozen pizza). 25,26Further, healthy food provides less than 5 g of salt/day.
Recognizing the huge burden of NCDs and related dietary risk factors in the Central Asian region, in 2021, the WHO European Office for the Prevention and Control of NCDs (WHO NCD Office), in consultation with national stakeholders in both countries, identified building capacity and providing technical support for the implementation of nutrition policies in schools as a priority for NCD prevention and control.The prioritization exercise was led by the Ministry of Health in both countries with support from the WHO NCD Office and was in line with the WHO Global Action Plan for the Prevention and Control of Non-communicable Diseases 2013-2020. 27chool nutrition policies (SNPs) targeting children ages 6-11 years and adolescents ages 12-19 years are developed and implemented at the state and local levels in different settings to improve the health and nutrition status of school children and youth. 22][30][31][32] SNPs have been shown to effectively address their targeted behaviors and health outcomes (e.g., reduced mean weight, increased consumption of healthy food, and reduced total fat and sodium intake 11,33 ) in other countries.However, it is yet to be seen if the adoption of SNPs will have similar results in Uzbekistan and Kyrgyzstan.The effective implementation of these policies is also needed to achieve population-level impact in both countries, 34 but there are gaps in our understanding of the implementation pathways and theories for supporting the effective implementation of SNPs in both countries and most other Central Asian countries. 34,35here are currently no comprehensive SNPs being implemented across other Central Asian countries (e.g., Kazakhstan, Tajikistan, and Turkmenistan). 36hese countries face complex malnutrition challenges among school-aged children, similar to Uzbekistan and Kyrgyzstan, with undernourishment and micronutrient deficiencies persisting in some areas alongside a rise in childhood obesity in others. 36Based on meetings and policy dialogues held across the region by the WHO Regional Office for Europe in 2021, only Kazakhstan and Tajikistan have a program that provides free school meals to primary school children, and this only covers a small percentage of schools nationally in Tajikistan.Similarly, only the 2 countries have laws on food safety, as well as regulations on nutrition in schools.It is not clear if the composition of SNPs have been shown to effectively address children's and adolescents' targeted behaviors and health outcomes, such as reduced mean weight and increased consumption of healthy food.school meals under these programs is evidencebased and if the programs are effective, as well as how to implement these programs at scale.
We describe a multicountry and multistakeholder collaborative process for developing SNPs NCD prevention and control in Uzbekistan and Kyrgyzstan targeting school-aged children ages 6-11 years, identify pathways for the effective implementation of these policies at scale in both countries, and provide lessons for other countries in the Central Asian region.The school children aged 6-11 years were prioritized based on political priorities in Uzbekistan and Kyrgyzstan and are universally targeted irrespective of sex, socioeconomic, disability, or vulnerability status.

METHODS
A multimethod approach combining document review, participatory theory of change workshops, and key informant interviews was applied to fully describe the SNPs, generate theories of change (TOCs) for the large-scale implementation of these policies in both Uzbekistan and Kyrgyzstan, and identify lessons for the effective implementation of these policies in both countries and across the region (Figure 1).The approach used for developing the TOCs that we briefly describe in this article follows a similar approach used for developing TOCs for large-scale implementation of schoolbased mental health programs. 37etween April 2021 and April 2022, relevant stakeholders involved with SNPs in each country were identified and convened to iteratively describe key interventions that were adopted as part of the SNPs, how and why these interventions were incorporated, and make explicit the pathways by which these interventions were expected to lead to their anticipated outcomes in both countries.This effort was led by the WHO NCD Office and facilitated by WHO Country Offices, which have been working to support the planning and implementation of SNPs across various sectors in both countries.Stakeholders identified in Uzbekistan (N¼16) and Kyrgyzstan (N¼21, n¼7 in a core group and n¼14 in an expanded group) included representatives from the following agencies: Ministry of Health, Ministry of Education, Ministry of School and Preschool Education, WHO Country Office, schools, teachers, school directors, and professional associations (e.g., family physicians) (Tables 1  and 2).The interest of parents was expressed by the teachers and school directors.
A document review worksheet was developed using Proctor's framework for specifying implementation strategies 38 and the Consolidated Framework on Implementation Research 39 to extract information on the interventions included as part of the SNPs in both countries and the process, settings, and activities involved in their implementation (Supplement).Stakeholders convened in the previous step were asked to complete the worksheets drawing on their experience and information from accessible policy documents and data sources based on their role as high-level ministry officials (9 government documents in Uzbekistan and 5 in Kyrgyzstan).
Based on the information extracted from the worksheets, initial drafts of theory of change (TOC) models were developed by the research team for specific interventions that formed the SNPs in Uzbekistan and Kyrgyzstan.The TOC models were developed by listing and sequencing the relevant overall health goals and outcomes at various levels (individual, community, and school) linked to the interventions and the policy advocacy activities that supported the adoption of the interventions.This approach followed the convention for developing TOC described elsewhere. 40The TOC models were further developed and validated with the stakeholders via a 90-minute participatory virtual workshop in each country.The workshops were facilitated by a study team member with expertise in implementation research and conducting TOC workshops.The workshop discussions focused on clarifying the specified outcomes and the relationships among the outcomes given the ongoing implementation experience in both countries.After the workshop, interviews were conducted with 2 key informants to further clarify the salience of specific facilitators and barriers to the implementation of SNP in both countries.The interviews were conducted virtually over Zoom by the study team, and each lasted about 60 minutes.
Last, a combined dissemination meeting was organized with the WHO NCD Office, WHO Country Offices, and key stakeholders from Uzbekistan and Kyrgyzstan as well as other countries from the WHO European Region to review and validate the final drafts of the TOCs, their key assumptions, implementation challenges and strategies, and contextualize the TOCs for the region (i.e., qualitatively evaluate whether the relationships, challenges, and strategies described were relevant for other similar countries).All workshops, meetings, and interviews were conducted in English and Russian with simultaneous interpretation.
We describe the SNP interventions that were implemented in both countries, the TOCs and implementation outcomes for supporting their large-scale implementation, key implementation challenges and strategies, and some key assumptions for successful implementation.

IMPLEMENTING A SCHOOL NUTRITION POLICY IN UZBEKISTAN Priority Interventions
The priority interventions as part of the SNP in Uzbekistan included the provision of healthy food for school-aged children through a school meal program and restrictions/prohibitions on the sale of foods in schools outside of the meal program.These interventions were accompanied by nutrition health education delivered through changes to the school curriculum to discourage unhealthy eating behaviors and facilitate the formation of healthy eating habits among school-aged children.
The interventions were developed by the Government of Uzbekistan in consultation with the relevant ministries (health and education), departments, and stakeholders, including parents and school administration.Under the program, the provision of healthy food for each school was outsourced to contractors who prepared and supplied the meals to schools according to stipulated standards.The meals were based on the following food products: meat, milk, butter, vegetable oil, wheat bread, eggs, cheese, quark (a type of curd cheese), vegetables, and other dairy products.Meals were guided by the recommended daily food consumption standards: with the ratio of proteins, fats, and carbohydrates set at 1:1:4 or 10-20%, 25%/-30%, and 50%-55%, respectively, and the ratio of calcium to phosphorus at 1:1.5. 25 The meals also included a piece of fruit as a side and were prepared to provide a proportion of the daily recommended caloric intake 60-65 kcal/kg for children aged 6-8 years and 35-45 kcal/kg for children aged 9 years and older. 25

Implementation Process and Activities
The meals were provided based on an approved monthly meal plan developed by the contractor in accordance with the daily nutritional and hygiene standards set by the Ministry of Health.Monitoring and enforcement measures were done to ensure that the contractors complied with the hygiene standards in terms of the food products and how they were prepared, the equipment that was used, and that the kitchen staff complied with the established rules for working in a food preparation area.

Theory of Change Model in Uzbekistan
The long-term goal for implementing the SNP interventions in Uzbekistan was to reduce the incidence of NCDs among children by targeting a reduction in the incidence of overweight and obesity among school-aged children, which had one of the worst prevalences observed (26% among both females and males) among countries categorized as NCD predominant, and reduction in cardiovascular diseases, stroke, diabetes, and cancers associated with poor nutrition later in life in adults.For the individual-level intermediate outcomes, the SNPs were anticipated to improve the habitual consumption of the targeted food at the nutrient composition and caloric standard and lead to changes in body mass index.For school-level intermediate outcomes, the SNPs were anticipated to improve the nutritional practices in schools and restrict access to unhealthy foods in school settings.These intermediate outcomes were mediated by implementation outcomes, including implementation fidelity to the nutritional standards and implementation guidelines by the food contractors, acceptability of the SNP interventions to key stakeholders (students, parents, teachers, and staff), and sufficient coverage of the SNP across eligible schools in Uzbekistan (Figure 2).

The crucial role of the Sanitary-Epidemiological
Welfare and Public Health Service under the Ministry of Health as a key implementer (both in managing school meal contracts and executing the policies around food restrictions in school) was clear earlier on, and their readiness (including human resources and technical and financial capacity) to undertake this role was identified as a key policy advocacy outcome along the pathway for achieving the longterm goal of the SNP interventions (Figure 2).
During the TOC development exercise, critical gaps in the implementation pathways for the SNP in Uzbekistan were discovered between the policy advocacy outcome and SNP interventions and between SNP interventions and the implementation outcomes, which may continue to impede the longterm goal as the program is currently being implemented.For example, the capabilities of agents within the Sanitary-Epidemiological Welfare and Public Health Service to manage food contracts while enforcing sale restrictions of competitive foods across schools could not be ascertained.Also, the tendering process for selecting contractors, training them, and monitoring their performance over time was not clear, and this process would likely vary across different subnational units.Hence, for the implementation pathways to work, additional implementation strategies may be necessary, including expanding the capability of the Sanitary-Epidemiological Welfare and Public Health Committee, developing and adopting clear training and performance guidelines for the contractors, provision of performance incentives to ensure that quality standards are met, and developing a monitoring plan to collect and track data on program performance and outcomes.
External context played a major role in how the implementation pathways played out.For example, a favorable sociopolitical context in Uzbekistan paved the way for the provision of policy instruments and the allocation of funds for the healthy school meals program. 41Similarly, the health system played an influential role in ensuring that both the intermediate and long-term health outcomes at the individual level were achieved by providing primary and secondary health care services (e.g., nutritional status tracking, nutritional counseling, diagnoses and treatment of nutritional diseases) and delivering nutrition interventions could shape nutritionally related health outcomes with or without the SNP. 42,43The food systems similarly influenced the interventions and implementation strategies, including the sourcing of food products constituted in the meal program; the pricing, marketing, and distribution of these products; and the availability, pricing, marketing, and distribution of unhealthy alternatives. 44oreover, the food system governed the production and access to various types of food outside of schools, including within the home environment, and contributed directly to nutritional practices at different levels.
Key assumptions that underlie the TOC for the large-scale implementation of SNP in Uzbekistan include the willingness of relevant ministries and stakeholders to prioritize SNP, availability of a sufficient number of competent contractors to implement SNP, stable food and commodity prices, and sufficient population coverage of the SNP for school-aged children in Uzbekistan.

IMPLEMENTING A SCHOOL NUTRITION POLICY IN KYRGYZSTAN Priority Interventions
The prioritized SNP in Kyrgyzstan entailed the provision of school meals to students in grades 1-4 (which overlap children aged 6-10 years) at the state and municipal public schools and the restriction of the sale of unhealthy food in schools.These interventions were done in accordance with decree no.372 of the President of Kyrgyzstan, which provides regulations on the organization of student meals in state and municipal public schools in Kyrgyzstan, and government decree no.673, which mandates statutory budgetary allocations for the provision of student meals for all students of grades 1-4 in state and municipal public schools in Kyrgyzstan.
About 18% of children in Kyrgyzstan suffer from malnutrition. 45The triple burden of malnutrition marked by stunting and vitamin and micronutrient deficiencies has been recognized as a major health concern affecting children in the country and is associated with about 22% of child mortality. 45 relatively high percentage of children and adolescents have iron and folate deficiencies (e.g., over 80% of females aged 10-18 years are folate deficient and about 40% of them are vitamin D deficient or insufficient). 46Hence, the school meals provided under the program are required per Kyrgyzstan law to be prepared from fortified food sources, such as fortified flour enriched with iron and B vitamins, including folic acid.

Implementation Process and Activities
In 2016, the Institute of Nutrition in the Russian Federation first developed technological charts that provided guidance on food and menu standards and revised them in 2019.They were approved by the Kyrgyzstan Ministry of Health and Ministry of Education and Science, which provided the charts to state and municipal public schools to develop menu plans following the recipe, nutrient, and caloric standards as described in the charts.
As of the writing of the article, 74% of the state and municipal schools in Kyrgyzstan (about 55% of targeted school-aged children) implemented the optimized school meal program (also referred to as the hot meal program), led by the Ministry of Education and Science in cooperation with the Ministry of Health and food assistance and technical support from development partners (UN World Food Programme also known as WFP and Mercy Corps).The country is administratively divided into regions and districts within regions.The intervention was funded and implemented through the Department of Education (DOE) operating at the district level across the country.The DOE administered relevant contracting tenders and oversaw the contractors that provided free meals according to the menu plans developed by the schools.Contractor selection was done by a DOE committee consisting of physicians, nurses, and representatives from local government and educational authorities.The heads of local state administrations and local self-government bodies organized the purchase of food products in accordance with the legislation on public procurement.
The remaining 26% of the public schools (encompassing about 30% of school-aged children in Kyrgyzstan) received only 7-10 soms (US$0.08-0.11)per child per day directly from the Government that could only cover milk, tea, kompot (fruit drink), and bun or cookies.Although in 2024, the per capita amount was increased to 14 soms (US$0.16),these schools continue to face challenges with the shortage of adequate kitchen equipment and water supply for meal preparation.

Theory of Change Model in Kyrgyzstan
The stakeholders in Kyrgyzstan prioritized reducing the prevalence of anemia (32% among females and 31% among males), which is one of the worst observed, 47 in addition to addressing overweight and other forms of malnutrition (Figure 3).The main causes of anemia among children and adolescents are iron and folate deficiencies, occurring mostly among females. 46[52] The main implementer in Kyrgyzstan was a multiagency group comprising the Ministries of Health, Education and Science, WFP, and Mercy Corp.The healthy meal plan development was also devolved to public schools in Kyrgyzstan.Meals were provided in Kyrgyzstan partly through contracts with food vendors and direct provision by schools with community involvement.
During the TOC exercise, critical gaps in the SNP implementation pathways in Kyrgyzstan centered around the capabilities of the DOE to manage school meal contracts and tendering process, training and developing performance guidelines for contractors and state and municipal public schools, and monitoring and enforcement of quality standards.Additional gaps observed in the SNP pathway included the absence of a consistent coordination mechanism between public schools and communities where meals were directly provided by schools and the lack of a standard approach for food sourcing to ensure stipulated nutrient standards were met.The additional implementation strategies and assumptions previously described for the SNP in Uzbekistan also applied to the SNP in Kyrgyzstan.In addition, standardization of the food sourcing approach across contractors and schools and the establishment of a coordination mechanism between public schools and communities may be needed to ensure the nutritional standards and implementation quality of SNP in Kyrgyzstan.

DISCUSSION
SNPs were being implemented to address the growing burden of NCDs in Uzbekistan and Kyrgyzstan.SNPs adopt a life course approach by prioritizing healthy nutrition and behaviors for school-aged children to minimize NCD risks for them as youth and adults later in life.For example, the SNP was expected to lead to a reduction in the incidence of NCDs and risks (e.g., obesity and anemia) among school-aged children in the short-to mid-term and adoption of healthy food habits among these age groups, which will contribute to the reduction in the incidence of NCDs associated with nutrition later in life.The SNP interventions did not specifically target known sex and age differences in these outcomes.For example, a higher prevalence of overweight and obesity among school-aged boys compared to school-aged girls and among those aged 5-9 years compared to those aged 10-19 years would likely persist 53 but would reduce for all school-aged children irrespective of sex and age over time.The interventions were being implemented through multistakeholder partnerships and multisectoral collaboration in both countries to achieve large-scale impact.

SNPs adopt a life course approach by prioritizing healthy nutrition and behaviors for school-aged children to minimize NCD risks for them as youth and adults later in life.
SNPs in both countries share some similarities.For example, both are based on nutritional standards consistent with available evidence (Korea, United States, and 5 continents) 54,55 and entail the provision of free healthy meals to school children and sale restriction of competitive foods in schools.Yet, SNPs differed in several ways.Whereas both countries are classified as NCD-predominant countries according to the Lancet Commission on Adolescent Health and Well-Being, the underlying NCD risks among children and adolescents differed slightly between countries. 47The political priorities for children and adolescent health in both countries were also different.Hence, the goal of reducing NCD in both countries was the same, but the pathways to achieving this goal (defined by the long-term outcomes) were different.For example, stakeholders in Uzbekistan prioritized reducing the prevalence of overweight/obesity among children and adolescents.Implementation activities had significant differences, which had implications for the implementation pathways to their large-scale effectiveness in both countries (Table 3).First, the main implementing organization was different in both countries, which carries with it differences in organizational culture, climate, and behavior that influenced the implementation process.The scale of the implementation was also different, essentially covering all schools in Kyrgyzstan but only selected schools under a special presidential program or a pilot project in Uzbekistan.This difference in scale, in turn, influenced the program's implementation arrangements.In Uzbekistan, the program was implemented mainly through a centralized and standardized contracting process, whereas Kyrgyzstan used multiple approaches, including both contracting processes and direct provision of meals by some schools with significant devolution of power and control to schools and local communities.The direct provision of meals by some schools in Kyrgyzstan may have become necessary because of the shortages of potential food vendors in the country to rapidly scale the program.The differences in scale of the program may have also impacted access to food sources to maintain the nutritional standards, with significant challenges in food sourcing in Kyrgyzstan relative to Uzbekistan.Whereas there is no single approach to implementing SNPs and large-scale implementation of programs is often opportunistic in most countries, the different SNP implementation arrangements provide important guidance on likely pitfalls to other countries in the region and emphasize the need for scale-up of nutritional programs to be planned and systematic.The different SNP implementation arrangements provide important guidance on likely pitfalls to other countries in the region and emphasize the need for scale-up of nutritional programs to be planned and systematic.

Continued
In Kyrgyzstan, there are debates around whether to contract or not to contract for school meals provision, especially given concerns around the fragmentation in contracting arrangements, inefficiencies in tender systems, lack of oversight for contractors and food standards, corrupt contracting practices, and limited human resources capacity.While contracting allows for rapid scale-up of the program compared to the direct provision of meals by schools with community involvement, the latter facilitates parents' and communities' engagement and ownership of the program and may be associated with better quality of food.Indeed, both strategic approaches have their advantages and disadvantages.However, if the contracting will be retained in the future, it will be important to develop a system for defining and enforcing contracting arrangements and tender systems to achieve impact.
Currently, contractors simply bid to supply meals based on a monthly nutrition plan and guidelines (which specify the nutrient and calorie standards) developed by the main implementer based at the Ministry of Health in Uzbekistan and Ministry of Education in Kyrgyzstan.The bid application is reviewed by a committee based on cost, quality, and safety standards, and the contractor is responsible for sourcing the food items from the market.However, performance and quality standards of the supplied meals are not regularly monitored and enforced by the committees, which is one of the main challenges facing the program in both countries.
If the contracting challenges cannot be addressed in the short-to mid-term, efforts targeted at addressing the shortcomings of the direct food provision may be prioritized, including establishing independent stores/warehouses that could be certified to provide fresh foods to schools to address the food sourcing challenges and setting up clear standards and protocols for school and community engagement to facilitate direct meal provision.For example, the certification of independent stores/ warehouses could involve third-party food safety audits that verify that fresh fruits and vegetables are produced, packed, handled, and stored in ways that minimize risks of microbial contamination based on regulatory practices drawn from experiences of other countries (e.g., U.S. Department of Agriculture, European Union General Food Law and Regulation, United Kingdom's Safety Act).These regulatory practices have been shown to be effective in improving the knowledge, attitudes, and behaviors of food handlers and distributors. 56n both countries, the SNP implementation pathways operated at different socioecological levels through various intermediate outcomes, including improvement of nutritional practices in schools and sale restriction of competitive foods at the school level; changes in nutritional knowledge and practices, increased participation of local community members in meal production and local governance of schools at the community level; and changes in consumption of targeted foods, metabolic measures, body mass index, and prevalence The challenges with implementing SNPs in Uzbekistan and Kyrgyzstan extend to other countries in the Central Asian region.For example, at a regional policy dialogue on SNP organized by the WHO Regional Office for Europe in 2021, many participants from different Central Asian countries highlighted the weak coordination between the Ministry of Health and the Ministry of Education.Similarly, the lack of performance standards for contractors, schools, and communities involved in SNP and lack of adoption or enforcement of nutritional standards continue to plague the success of SNP in Kazakhstan, one of the only countries from the region that has a school meal program. 57ence, the lessons and strategies discussed in this article for SNP in Kyrgyzstan and Uzbekistan may have relevance to other countries in the region.
The availability and cost of different types of food in schools are influenced by the food system, 58 including actors involved in agricultural production, food importation, and aid capacities.For example, the Global Food Security Index ranked Uzbekistan 73 of 113 countries in 2022 and lists some of the biggest challenges to food availability, including agriculture producer prices, empowering of women farmers, and limited irrigation infrastructure. 59,60These issues may have been further exacerbated by the armed conflict in the region and inflation, which has pushed up food and agriculture input prices globally. 61While the current average cost of providing school meals in the region is unknown (estimated at US$0.10-0.15 in Kyrgyzstan in 2017), 62 SNP will clearly require considerable and continuous funding to be sustainable.Hence, innovative funding strategies may be needed to sustain the school meals program under SNPs in both countries and across the Central Asian region.
Further, the production and distribution of food are governed by market forces and sensitive to market fluctuations in both countries and across the region.The capacity to process food in both countries is also limited despite the agricultural sector being a leading employer. 63,64Agents from the education and health sectors interact with food suppliers through market interactions, and none of the countries in the region, except for Kyrgyzstan, has any regulations on how unhealthy food (e.g., highly processed food rich in trans-fat) are marketed to children outside of schools. 36Hence, broader policies, including those ensuring fair market prices, consumer protection, and safe marketing practices, are needed to ensure that the goals of the SNP are achieved.
While still likely to evolve, the TOCs, outcomes, strategies, and pathways we describe are relevant for initially guiding a systematic evaluation and learning on large-scale implementation of SNP in both countries and other low-and middle-income countries.For next steps, the description of the SNP and implementation processes will be used to package and test selected implementation strategies for addressing gaps in the TOCs and to develop tools and mechanisms to systematically learn and improve the policy outcomes in both countries and guide the adoption of similar policies in the region.

Limitations
The approach as applied in this article has some limitations.For example, the TOC workshops were conducted virtually (due to COVID-19 pandemic restrictions), which may have limited the discussions around the programs and their implementation pathways and the ability to form consensus on key outcomes.We tried to overcome this limitation by prepopulating the TOC diagrams based on the document synthesis before the meetings so that the workshop time could focus on validating the nature and forms of different outcomes and relationships among them.It should also be noted that the TOC only represents factors that emerged from the group of stakeholders involved in the group modeling process and may have omitted other important factors for determining the specified outcomes (e.g., the role of food systems).Moreover, the contribution of a school-based meal program and nutritional practices may not entirely account for the specified long-term outcomes, given the multifactorial causal factors that contribute to NCD incidence and the individual variations in how these factors combine to lead to NCDs.

CONCLUSION
Adoption of SNPs in Uzbekistan and Kyrgyzstan is a first and important step to addressing nutritionally related NCD risk factors among school-aged children.However, both countries have experienced multiple challenges in the large-scale implementation of SNPs.Through a multimethod approach, we described TOCs for SNPs in Uzbekistan and Kyrgyzstan to identify key interventions, outcomes, implementation gaps, and assumptions that should be addressed and targeted with implementation strategies to facilitate the large-scale implementation effectiveness of these policies in both countries and other countries in the Central Asian region.Beyond SNPs, there is scope for broader and more comprehensive nutrition reforms that will entail the whole of government and sectors to address the nutrition needs of specific populations and both the proximal and distal causes of nutritionally related NCDs, including causes in the food systems and environment.
